Abstract
Apparatuses and methods described herein relate to brazed heat exchangers, which may be used for example in a heating, ventilation, and air conditioning system (HVAC) system and/or unit thereof. The heat exchanger includes a fluid flow structure to allow a fluid stream, for example a chilled fluid stream to exchange heat serially with more than one refrigerant circuit, where each refrigerant circuit is a distinct and independent refrigerant circuit. Generally, an apparatus to exchange heat serially with more than one heat exchange fluid circuit includes an internal flow path that allows a working fluid to flow through a first brazed heat exchanger, through one or more internal routing channels, and through a second brazed heat exchanger.
